Java EE (Java Enterprise Edition) General Discussion

Hi,

I am using oreilly's MulitpartRequest to upload a file, however I am having difficutly trying to get the actual Name of the file itself. I am using the following code. I only have one file to upload so it is a little different from the examples I have seen. I am using MultipartRequest getParameter method to get the values from the other form fields..

File fileNm = null;

...

//this is inside my doPost()
MultipartRequest multi = new MultipartRequest(request, "C:\\files", 50 * 1024);

String strIndustry = multi.getParameter("frmIndustry");
String strCompany = multi.getParameter("frmCompany");
String strCollabType = multi.getParameter("frmCollaboration")
String strFileSource = multi.getParameter("frmFileSource");

fileNm = new File(strFileSource);
displayfileNm = fileNm.getName();

String file = multi.getFilesystemName(strFileSource);
File f = multi.getFile(strFileSource);
....

//then I am testing to see what I get using this.
output.println("File name: " + displayfileNm + "<br>");
output.println("File name: " + file + "<br>");

I know there are many ,many posts about using MulitpartRequest but I have not been able to find a resolution or answer to this problem. The servlet compiles, but when I try to run it I get::

java.lang.NullPointerException
at java.io.File.(File.java:180)
at FileUpload.doPost(FileUpload.java:67)
at javax.servlet.http.HttpServlet.service(HttpServlet.java)
etc.......


Any idea why I am not getting the file name??

Any help would be greatly appreciated.

Thanks
